Cheapest ACA plans in Mississippi for 2026

Cheapest plans by metal tier

Lowest 2026 monthly premium for a single 40-year-old non-tobacco user, on-exchange, before any subsidy. Per-age figures derived from the CMS QHP Landscape file using the HHS standardized age-rating curve (45 CFR 147.102).

The actual cheapest plan in major counties

Same data the search returns: carrier, plan name, monthly premium, individual deductible, individual MOOP. Computed for a single 40-year-old non-tobacco user, before any subsidy. Catastrophic plans excluded because adults 30+ typically need a hardship-exemption certificate to enroll.

The actual cheapest plan for a family of four

Two 40-year-old adults and two kids in the 0-14 age band, before any subsidy. Carrier, plan name, premium, deductible, and MOOP exactly as the search would return them.

Subsidies: federal APTC only (no state premium subsidy)

Mississippi does not operate a state-funded premium assistance program, state reinsurance program, or §1332 waiver for the individual market. Marketplace help is federal only:

1. Federal Advance Premium Tax Credit (APTC). Households 100-400% FPL on the PY2026 standard ACA contribution curve. The ARPA / IRA enhanced subsidies expired 2025-12-31 and are not in effect for 2026, so the hard 400% FPL cliff is back.
2. Federal cost-sharing reductions (CSRs). Households 100-250% FPL enrolled in a Silver plan receive reduced deductibles, copays, and out-of-pocket maximums automatically.

Mississippi has not adopted ACA Medicaid expansion. Mississippi Medicaid eligibility for non-disabled adults is extremely narrow (parents below roughly 27% FPL, pregnant women, and categorically needy groups), which leaves one of the largest coverage gaps in the country on a per-capita basis. Adults earning below 100% FPL who are not Medicaid-eligible fall into the coverage gap and cannot receive federal premium tax credits either.

Catastrophic plans in Mississippi follow federal rules

Mississippi follows the federal ACA default: Catastrophic plans are available to enrollees under age 30, or at any age with a hardship / affordability exemption. The PY2026 federal auto-expansion applies: adults 30+ automatically qualify when the lowest-cost Bronze plan exceeds the affordability threshold. APTC does not apply to Catastrophic plans.

Tobacco surcharges follow the federal 1.5x default in Mississippi

Mississippi applies the federal ACA default (45 CFR 147.102): carriers may charge tobacco users up to 50% more than non-users (a 1.5-to-1 rate ratio). The Mississippi Insurance Department reviews rate filings under Miss. Code Title 83. No Mississippi-specific cap below the federal 1.5x ceiling has been identified. Federal APTC does not offset the tobacco portion of the premium.
